METAL-REFORMING METHOD AND APPARATUS.

Application filed February 11, 1924, Serial No. 691,965.

This invention relates to the production of shapes especially in arc lengths. I

This invention has utility when incorporated for handling straps or strips of sheet metal for making rings thereof in special configuration in cross section, as in the production of demountable rims for motor vehicle tires.

Referring to the drawings: Figure 1 is a side elevation of an embodiment of the invention in a tire rim forming machine; 1

Fig. 2 is a perspective View of a strip of Fig. 3 is Fig. 1; V

Fig. 4 is an elevation of the machine from the left of Fig. 3

Fig. 5 is a section on the line V V Fig. 6 is a partial section on the line VI-V-I Fig. 3;

a plan view of the machine of .Fig; 7 is a partial section on the line VIIVII Fig. 3; and

Fig. 8 is a sect-ionthrough the die on the line VIIIVIII Fig. 3.

Upon main base 1 is mounted motor 2 having shaft 3 carrying sprocket 4about which extends sprocket chain 5 to sprocket wheel 6 on shaft 7 This shaft? is carried by frame members 8, 9. Pinion 10 on this shaft 7 is effective to drive gear 11 on shaft 12 extending through frame members 8, 9, 13 and 14.

These frame members 8, 9, 13, 14 are fixed to the mainbas'e 1 by bolts'15, and are further braced as to each other by tie members 16, anchored by bolts 17 On this shaft 12 between the members 8, 9, is gear 18 in mesh with gear 19 therebelow on shaft 20 extending parallel to the shaft 12 and through the main frame members 8, 9, 13, 14.

Primary guide and push roll 21, fast on the shaft'12 has its flanges 22 overlap opposing roll 23 on the shaft 20. These rolls 21, form an initial or primary pair of rolls for receiving strip sheet metal stock. Each of these rolls21, 23, is power driven, and the stock is forced from this pair ofrolls of the roll forming train to the next succeeding pair of rolls; p

Mounted on the shaft 12 on theopposite side of the machine fro m the gear 11 is gear 24, in mesh with gear 25' on shaft 26, carried by the frames 8, 9, 13, 14. This shaft Renewed October 1, 1928.;

26 has pinion 19 thereon in mesh with pinion 18 on shaft 27. The shaft 27 carries roll 28, opposing companion roll29 on the shaft 26. These rolls 28, 29, form the second pair of the roll train, and initiate the transverse flange forreforming of the strip material.

' Mounted on the shaft 27 is gear 30 inmesh with gear. 31 on shaft 32, extending through the frame 8, 9, 13,14. This shaft 32 between the frame members 8, 9, has pinion 19 in mesh with pinion 18 on shaft 33, parallel to shaft 32. This shaft 33 carries reforming roll 34, opposing companion roll 35 on the shaft 32, as the third pair of reforming rolls in this rolling train. This third .pair in-- creases the degree of transverse reforming, and as shown has reduced the overall width of the strip material by so-doing. The shaft 33 on the side of the frame carrying the gear 24 is provided with gear36, in mesh with gear 37, on the shaft 38, extending through the frame members8, 9, 13, 14. This shaft 38 has thereon pinion 19, between the frame members8, 9, in mesh with pinion 18 on the shaft 39, parallel to the shaft 38. ]On this shaft 39 is'reforming roll 40, opposing com panion roll 41-. These reforming rolls 40, 41,

provide the terminal pair of reforming rolls "shafts, so that the positions between the roll pairs may be nicely adjusted to take care of the thickness of stock being operated upon. This degree of proximity of the rolls is such that there is not only a firm holding of the sheet stock but in the forcing or propelling of the stock through this train of rollers there is incidental to the reworking of the material a building up temperature therein to quite a degree, even with stock starting cold, or normal temperature, as fed in the machine. This building up of the temperature in the stock makes it more susceptible for the extreme reforming in the latter stage. Pivot mounting 42 for die sections 43, 44, is so, disposed that advance or entrance porti0nf45 of these die sections 43, 44, are in close proximity to the stockas leaving the region of. reforming between the terminal pair of reworking falls 40, 41'.
